CARLOS EGGELSTON, OF ST. LOUIS, MISSOURI.

BRACKET OR SUPPORT FOR SHELVES, DESKS, AND TABLES.

SPECIFICATION forming part of Letters Patent No. 382,296, dated May 8,1888,

Application filed July 12, 1887. Serial No. 244,074.

To all whom it may ooncerm Be it known that I, CARLOS EGGELSTON, acitizen of the United States, residing at No.

2354 Mullauphy street, in the city of St. Louis and State of Missouri,have invented certain new and useful Improvements in Brackets orSupports for Shelves, Desks, and Tables; and I do declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and tothe letters and figures of reference marked thereon,which form a part ofthis specification. This invention relates to brackets or supports forshelves, desks, tables, and the like; and it consists in the peculiarcombinations and the construction, arrangement, and adaptation of parts,all as more fully hereinafter described, and then particularly definedby the claims.

The object of the invention is to provide a bracket which may beadjusted to any desired height or to any desired angle, which will becheap in its constructionand durable and efficient in the use for whichit is intended.

The same is clearly illustrated in the accompanying drawings,formingapart of this specification, and in which Figure 1 is a sideelevation of a desk provided with my improved supports. Fig. 2represents in a similar view an illustration of the use of my supportsfor store-shelves and the like for the display of goods. Figs. 3and 4represent front and side views, respectively, of the rack-bar I preferto use in connection with my bracket. Fig. 5 is a side view of thebracket itself. Fig. 6 is a like view of the same with the overhangingarm attached. Fig. 7 represents a side view of the ratchet lock-joint.Fig. 8 shows the parts of the same detached, but in their relativepositions. Fig. 9 represents a top plan of the bracket engaged with therack-bar, the latter being shown in cross-section.

Referring to the details of the drawings, A represents a rack-bar,whichin cross section is substantially T-shaped, as shown in Fig. 3,the basea of which is designed to be secured to a proper support in any suitableway, preferably by means of screws engaging the open- (No model.)

sided holes a, formed in the edges of said base, as shown. The head I)of this rack-bar is provided upon its rear face with the ratchet-teethA, which are hidden from view by said head.

The bracket B is formed of the main piece B',designed to support the bar0, which may be formed integral with or secured to said bracket. Thisbar G forms a support for the shelf D or desk E, as the case may be, andis provided with open slots or holes 0 with which the screws engage tosecure it to said desk or shelf. The main piece B is diminished inthickness at its rear end to form the disk If, one side of which isprovided with ratchetteeth b. Shoulders c are formed by the diminishingin thickness of the'part B, the object of which will hereinafter appear.

F/ is a disk of substantially the same size as the disk bfand has eitherformed with or secured to it a jaw, e, of substantially the shape shownand formed at its rear end with a lug .or extension, 6, provided uponits inner face with teeth 0 F is another disk of the same size as thedisks 1; and E, and provided on its inner face with ratchet-teeth F,which engagethe teeth I) on the central disk. This disk F is also formedwith or has attached to it ajaw,f, provided with a lug or extension, 9,formed with teeth 9. These three disks are provided at their centerswith an opening, h, through which passes the screw or bolt G, providedon its end with an adj listing-nut, G.

The exposed partsof the main piece, B, the disks E and F, and the'jawsmay be made as faneiful or ornamental in appearance as desired.

In practice thejaws c and f are slipped over the head of the rack-bar,when the teeth on said 3' aws will engage the teeth on the rack-bar, andthus hold the bracket and its supported weight in the desired-position.

When it is desired to raise or lower the brackehthe teeth on the saidrack-bar andjaws are disengaged,when the said bracket is free to bemoved up or down. It will be observed that there is space left betweenthe head and base of the rack-bar, and between the extensions of thejaws and the end of the bar (3, to allow of a slight play of the saidhead, for the purpose of disengaging the said teeth, as shown in Fig. 9,and to facilitate such disengagement I have provided thedownwardly-extending arm I on the disk F,which arm may be of anypreferred form and as ornamental as desired.

To change the inclination of the bar C and the shelf, desk, or whateverit may be used to support, it is only necessary to loosen the nut G,when the bar can be tilted to any desired angle,when by tightening thenut the ratchetfaced disks will lock and securely hold the bar in itsadjusted position.

K is a bracket designed to be secured to the bar 0, as shown in Fig. 6,and is provided with an overhanging arm, L, which may be rigid with itor secured thereto by a joint, similar to that above described inconnection with the bracket B.

M is another arm secured to the outer end of the arm L by a flexiblejoint, preferably similar to that above referred to, and is providedwith one or more openings or sockets, m, designed to receive and holdone end of a rod or rods, N, upon which rods may be displayed goods,which, when desired, may be lowered by simply loosening the set-screw ofthejoint, as heretofore described in connection with the bracket 13. Ifdesired,the shoulders 0 may be made slightlycam-shaped, so as to bindthe disks E and F, thus serving to relieve the bolt G of strain.

It will be observed that by the construction above described I provide asimple, cheap bracket, which can be readily changed to accommodatepeople of different heights, which change can be readily made by anyperson with ease, making it specially desirable for use in stores wherelady clerks are employed.

Various modifications in detail may be made without departing from thespirit of my invention.

Having thus described my invention and set forth its merits, what Iclaim is 1. A rack-bar, A, formed with base a, and a head, I), havingteeth A upon its rear face to conceal the same behind the head,substantially as and for the purposes set forth.

2. The combination, with a rack-bar, A, having a base, a, and providedwith a head, 12, formed with teeth A upon its rear face, of a bracketformed with rearwardly extending lugs provided with right-angledextensions formed with teeth adapted to engage the teeth of saidrack-bar, substantially as described.

3. The combination, with a rack -bar, A, having a base, a, and providedwith a head, 1), formed with teeth A upon its rear face, of a bracketformed with teeth engaging the teeth of the rack-bar, and a dependingarm, I, as shown, on said bracket, for the purpose of disengaging saidbracket and bar, substantially as described.

4. The bracket consisting of the main piece B,formed withratchet-dislgthe disk E, formed with toothed jaw and fitting on one sideof said main piece, the disk F, formed with ratchet face and toothed jawand fitting against the ratchet-disk of said main piece, and means foradjustably securing said parts together, substantially as and for thepurpose specified.

In testimony whereof I affix my signature in presence of two witnesses.

CARLOS EGGELSTON.
